A type of MIPS instruction used mostly for arithmetic and logic functions.

The first 6 bits (bits 31-26) as in all MIPS instructions are the opcode.

The next 5 (25-21) after that represent the first source register. (MIPS processors have 32 general purpose registers) The following 5 (20-16) are for the next source register, and the next 5 (15-11) after that designate the destination register of the instruction.

The next 5 bits (10-6) are the 

shamt
field, which is used to shift the result up to 32 bits. The last 6 (5-0) are the 
funct
field, used to expand perform most arithmetic and logic operations with a single opcode. For example, the or and and instructions have the same opcode, but different values in the funct field.

Quite possibly the most frequently ported game in existence. Versions of it exist on:

Nintendo Entertainment System(NES)
Super Nintendo Entertainment System(SNES)
Nintendo Game Boy
Sega Master System
Sega Game Gear
Sega Genesis
NEC TurboGrafx 16(TG16)

The only contemporary system I am aware of that it is not on is the Atari 7800. Poor schmucks.

A horizontally-scrolling space shoot-'em-up, developed as an arcade game by Irem (NOT Nintendo!) in 1987 and ported to nearly every home computer, console and handheld available, from the ZX Spectrum to the Sony Playstation. R-Type introduced a number of ideas that have often been copied since, such as a level involving flying around the outside of a much larger spaceship, and a weapon that is charged up by holding down the fire button.

The enemies (the evil alien Bydo Empire) are in Irem's biomechanical style, with a mixture of traditional spaceships and massive alien creatures (such as the iconic first end-of-level boss). Knowing they were onto a winner, Irem put out a number of sequels/remakes (R-Type Leo, R-Type II, Super R-Type) as well as several games with a similar style (such as X Multiply). Tecnosoft's later Thunder Force games are probably the closest thing to an immediate successor to R-Type, and contain numerous 'homages' to parts of the original game.
